Slightly off topic sorry OP, is it possible to cancel all health accident coverage from a policy? I have this coverage through life insurance and my works health insurance.

My policy says 500$ a year for this, which I think is bullshit.

The accident benefits are mandatory. They will extend to cover any occupant of your vehicle (unlike your life/work benefits package). So there is still value in having them. You are not allowed to decline/exclude them.
